efficency of ball mills

In general, ball mills can be operated either wet or dry and are capable of producing products in the order of100 μm. This represents reduction ratios of as great as100. Very large tonnages can be ground with these ball mills because they are very effective material handling devices. Ball mills are rated by power rather than capacity
